S-94709A131 0.475" ID x 0.875" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior Sealing Performance - Neoprene rubber seal (Durometer 65A) bonded to 18-8 stainless steel creates a reliable, long-lasting barrier against moisture, dust, and contaminants
• Exceptional Temperature Resistance - Maintains sealing integrity across extreme operating conditions from -40°F to 250°F for demanding industrial environments
• Corrosion-Resistant Construction - 18-8 stainless steel base provides excellent resistance to rust and chemical degradation in harsh applications
• Precision Fit for 7/16" Screws - 0.475" ID ensures secure fastening with minimal play, reducing vibration-related loosening
• Durable Metal-Rubber Bond - Permanent bonding between stainless steel and neoprene prevents separation under stress for consistent performance
• Comprehensive Compliance - Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards for safe use in regulated industries
• Optimized Dimensions - 0.875" OD with 0.179-0.214" thickness provides optimal load distribution and sealing surface area

Professional Applications & Engineering Value

These metal bonded washers deliver critical sealing solutions where standard washers fail. The 18-8 stainless steel construction bonded with neoprene rubber seals addresses common industrial challenges including fluid leakage, vibration-induced fastener failure, and environmental contamination. Engineered for 7/16" screw compatibility, they provide reliable performance in equipment exposed to temperature fluctuations, making them ideal for HVAC systems, automotive assemblies, outdoor machinery, and processing equipment. The black neoprene seal offers excellent UV and ozone resistance, while the metal-rubber bond ensures the seal remains intact during installation and throughout the product lifecycle, reducing maintenance frequency and downtime in critical applications.
